Definitions

  • the invention relates to a connection device for a Suction bottle for sucking off wound fluids during wound drainage.
  • a pre-evacuated feeding bottle is preferred with vacuum indicator, via a connecting hose with a perforated wound drainage tube connected in an airtight, closed wound cavity is inserted.
  • connection device usually used is a bare hose, with one end on a connecting piece on the feeding bottle and with his other End connected to a connector on the wound drainage tube becomes.
  • a clamping device is used to interrupt the connection device.
  • a generic connecting device of the beginning mentioned type is known from FR-A-2208545.
  • the Connection device has a breakthrough circular cylindrical body screwed onto a bottle can be. Wound fluids can enter the bottle be sucked in.
  • the required vacuum in the bottle can be regulated by means of a membrane.
  • the Membrane is circumferentially through the free, peripheral edge of a circular cylindrical hollow cylinder closed on one side pressed tightly against the cylindrical body.
  • the membrane is in the space between the pistons and present in the body. Unless the piston from the membrane is moved away, forms in the space between the piston and Membrane a differently large negative pressure.
  • the invention has for its object a connection device to specify for a feeding bottle that simple is designed and the problem-free replacement of a connected suction bottle allowed.
  • connection device is technically simple designed. Because completely through the membrane closed central opening at least one more no further opening through the membrane at the same time is closed, for example wound fluid can still flow into the connection device and, for example drain into an overflow vessel. The drainage of wound fluid so there is no need to interrupt from a wound, if a suction bottle filled with wound fluid against a new feeding bottle is to be replaced.
  • connection device is thus as Suction regulators trained by their Membrane depending on the on their interior and Pressures acting a central opening in an outer surface Membrane carrier releases or closes.
  • the pressure on the The outside can be adjusted in that the membrane carrier sealed with membrane in a hollow cylinder which is closed at the end on which Side of the membrane.
  • the back and forth is preferably carried out Pushing the membrane over by a rotary movement a screw thread between membrane support and hollow cylinder is led.
  • the end wall has of the hollow cylinder centrally an elastic sealing part which then presses on the membrane when the membrane carrier completely moved to the closed end of the hollow cylinder is what causes the membrane to the central opening in the Presses the membrane carrier and closes it. That’s it possible the connection between a feeding bottle attached to the central opening is connected, and the wound drainage tube to interrupt.
  • connection with central opening for the feeding bottle and the connection for the wound drainage tube has the membrane carrier preferably still further connections, namely for a vacuum indicator and / or for an overflow vessel, the central opening continues to flow into the wound secretion is closed.
  • a plurality of openings can also be present on a connection device in which the membrane is not slidable in the hollow cylinder, like this e.g. B. described in German patent application 37 24 483 is.
  • connection device 50 has a hollow cylinder 51 on one side through an end wall 52 is closed. Runs in the hollow cylinder 51 Membrane support 53 with a membrane 54 on the membrane support is attached, which is directed against the end wall 52 and which seals against the hollow cylinder 51. The move the membrane carrier 53 takes place via a screw connection, which is formed by two pins 55 on the membrane carrier 53, through two helical recesses 56 in the hollow cylinder 51 grab.
  • the membrane carrier 53 is designed so that it is on the front side, to which the membrane is attached, a circumferential Bead 57 has. One ends centrally in this end face Central opening 58, with a shut-off nozzle leading to the outside 24 communicates. Because the bead 57 is present is, close this, the mentioned end face 59 of the Membrane carrier 53 and the inside of the membrane 54 one Cavity 60, which is accessible through the central opening 58 for as long is as long as the membrane 54 is not so far against the end face 59 is deformed so that it is the central opening 58 closes.
  • the openings of three other sockets namely one Inlet nozzle 23, a vacuum indicator nozzle 61 and one Overflow nozzle 62.
  • the associated openings are an inlet opening 63, a measuring opening 64 or an overflow opening 65.
  • a vacuum indicator is on the vacuum indicator connector 61 and an overflow vessel to the overflow nozzle 62 connected. Both devices should be small-volume so that a vacuum quickly builds up in them.
  • the inlet port 23 is with a perforated wound drainage tube in connection and the shut-off nozzle 24 is on a feeding bottle connected.
  • the connection is made in a position of the connection device in which the membrane carrier 53 close to the end wall 52 of the hollow cylinder 51 stands so that an elastic sealing member 66, which is on the inside the end wall 52 is attached, the membrane 54 against the central opening 58 presses. Now becomes the hollow cylinder 51 screwed to the membrane carrier 53 moves its end wall 52 away from the membrane 54, whereby a negative pressure builds up in the space in between.
  • the pressure in the cavity 60 at which the membrane 54 from the central opening 58 takes off not only depends on the pressure on the Outside of membrane 54 and the pressure at the central opening 58 from, but also from the elastic force acting on the membrane 54 pulled over the bead 57 is exerted.
  • the extent of the negative pressure in the cavity 60 can thus be determined preselect the default of this elastic force and by the Moving the hollow cylinder 51 and membrane carrier 53 against each other fine tune.
  • the elastic force can influence the material of the membrane 54 or its Form can be taken or the height of the bead 57 and its height Inner diameter can be varied.
  • the adjustability serves between Hollow cylinder 51 and membrane supports 53 for fine adjustment a desired negative pressure.
  • membrane carrier 53 and hollow cylinder 51 can be made using any sliding construction. So instead of pegs that reach through recesses there are also shorter cones that are single [i in helical grooves in the inner peripheral wall of the Intervene in the hollow cylinder. Any other screw connection you can choose between hollow cylinder and membrane support. Locking connections can also be used where fixing in a new position after moving through Locking forces.
